You might want to toss those iron-fortified vitamins, because absent a diagnosed deficiency too much of a good thing can be bad.
Dietary iron imbalances either way spell trouble for healthy cells, triggering a chain of cellular events in the brain that increases the odds of developing Parkinsons disease, a degenerative condition affecting movement and balance in more than 1 million Americans each year. But excessive iron levels are worse -- much worse.
The findings from a study by Florida State University scientist Cathy Levenson are described in "The Role of Dietary Iron Restrictions in a Mouse Model of Parkinsons Disease" and will appear in an upcoming edition of Experimental Neurology. Levenson is an associate professor of nutrition, food and exercise sciences in FSUs College of Human Sciences and a faculty member in both the Program in Neuroscience and graduate program in molecular biophysics. "We define our work here at the cellular level," said Levenson from her laboratory at FSUs Biomedical Research Facility. "Our primary research objective is to better understand how trace metal imbalances, which are associated with neuropsychiatric and neurodegenerative diseases, affect the molecular mechanisms that regulate gene expression."

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
